R: Trim something other than whitespace

str_trim_anything {strex}

R Documentation

Trim something other than whitespace

Description

The stringi and stringr packages let you trim whitespace, but what if you want to trim something else from either (or both) side(s) of a string? This function lets you select which pattern to trim and from which side(s).

Usage

str_trim_anything(string, pattern, side = "both")

Arguments

`string`	A character vector.
`pattern`	A string. The pattern to be trimmed (not interpreted as regular expression). So to trim a period, use `char = "."` and not `char = "\\."`).
`side`	Which side do you want to trim from? `"both"` is the default, but you can also have just either `"left"` or `"right"` (or optionally the shortened `"b"`, `"l"` and `"r"`).

Value

A string.

Examples

str_trim_anything("..abcd.", ".", "left")
str_trim_anything("-ghi--", "-")
str_trim_anything("-ghi--", "--")
